To all whom it may concern o. y

lBe it known that l, Gusrar ns'rei/r, a subject oi2 the Kin of Sweden,residing at Stockholm, in the ingdom oi Sweden, have invented certainnew and useiul improvements in Machines for Packing Cigarettes orSimilar Articles, ot which the following is a s ecication.

'ilhis invention relates to a machine tor packing` cigarettes or similararticles 1n paper-bags, boxes or the like of that class, in which thecigarettes by a suitable mechanism are mounted in a predeterminednumloer in a portioning chamber or chute, "from which they are thenpushed into the paperloag' or box. According to the invention themachine is provided with a eeler mechanism, which is located at .thesaid portioning charnberand, it the chamber does not contain thepredetermined number ot cigarettes causes a device to eiiect a mark inthe paper-bag, which has received the incomplete set ot'cigarettes, sothat the said paper-bag may be removed trom. the other bags, containingthe proper number ci cigarettes.`

lin the accompanying drawings Fig. i Shows in a side view partially insection a cigarette packing machine arranged in acp cordance with thisinvention. Fig. 2 is a section on the line 2-2 in Fig. l. Fig. 3 showsthe feder-mechanism and Figs. t and 5 show a marking device in twodiiterent positions.

in the drawings the invention applied to a machine ot that class, inwhich the cigarettes l are located in a hopper 2 and fed from the sameinto two vertical channels 3 and 4, separated from one another by apartition wall 5', bytwo rotating drums t3 and 7 provided in theirperiphery with grooves 3. From the said drums tand 7 the cigarettes arecaused to pass into the channels 3 and d by suitable guiding members 9,1l and l2. The partition wall 5 extends downwards into a portioningchamber bottom 23 of the said chute is carried by a rod 24, the top endoi which has a slot for the wall 5. The rod 2i is movable in suitableguides and -is engaged by a lever arm 25, iixedto a shaft 26. A secondarm 27 is iixed to the shaft 26 and, actuated by a spring or the like,not shown bears against a cam disk 28, provided on a rotating shaft 29.At the top of the chute is shown i922. Serial No. teti.

22 two knives 30 and 31 are provided, one at each side ot the chute.'lhe said knives are carried by arms V32 and 33 respectively, swingablymounted on shafts 34 and 35. Arms 32 and 33 are provided with toothedsegments 36 and 37, engaging one another. A spring 38 fixed to thetraine of the machine and an arm. 39 connected with the arm 33 tends tomove the knives 30 and 3l toward one another. An arm t0 is connectedwiththe arm. 32 and bears against a cam disk 41 tired on. the shaft 29.

. in Fig.. l a portion ci ten cigarettes is located in the chute k22,iive on each side ci the wall 5, and the knives 30 andL 31 arecigarettes, are located in pockets provided 1n a drum 4t2, whlch isrotated step by step in the direction, indicated oy the arrows in Figs.d and 5. is one oi the said pockets is opposite to the chute 22, thepaper-bags 43 contained in the said partition is pushed by an arm or thelike not shown upon a nozzle di, connected with the chute. A plunger 45,actuated in any suitable manner, then ushe's' the said portion ot'cigarettes into the paper-bag and returns the latter into the pocket.liter the end flaps of the bag has been folded and pasted together,which is eii'ected during the continued rotary motion ci the drum 42,the bag is removed from the pocket. These operations may be effected inany suitable manner.

fitter the cigarettes have been pushed Vfrom the chute 22 in thedescribed manner,

and the plunger 45 has been returned, the bottom 23 is raised to theknives 30 and 3l. The knives 30 and 31 are then withdrawn quickly by theearn disk il, whereupon the cigarettes contained in the channels 3 and lfall down unto the bottoni 23. The latter is then lowered slowly by thecam disk 28,

this inventlon are provided, one at each side of the chute.` The saidfeelers are swingably4 mounted on the shafts 34 and 35 and acted upon bysprings 50 and 51, which tend to move the feelers inwards into thechute. Feelers 46 and 47 are provided with arm 52 and 53, adapted to/actuate a lever 54, 55 fixed to a shaft 56 and co-operatng with arotating cam disk '57. While the notch 58 of the said cam disk 57 passesby the lever arm 55, the lfeelers 46 and 47 are permitted to moveinwards, acted upon by the springs 50 and 51. lf the chute 22 is iilledup with cigarettes, the teelers will bear against the uppermostcigarettes in the chute andk no motion of the/feelers will take place.lf, however, one of the compartments of the chute 22 or both thecompartments do not contain'the proper number ot cigarettes, as is thecase with the right hand compartmentyin Fig. 3, the feeler 47 is swunginward by its spring 51, as shown in F ig. 3. Arm 53 ot the feeler 47then iorces the lever arm 54e downwards against the action of a spring72. ',lo the shaft 56 a second arm 59 is hired, which, consequently, isforced downwards together with the arm 5d. 'llhe said arm 59 actuates anarm 60 of a catch 61, which is swingably mounted on a pin 62 and by aspring 63, hxed to the frame of the machine, is held in engagement witha projection 6a provided on an arm 65, swingably mounted 0n a pin 66.Arm 65 has a roller 67, which, by a spring 68, hired to the arm 65 andthe trame of the machine, is forced against a cam surface 69, providedon the drum d2. ln 'Figs i and 5 some pockets of the drum containingbags are shown. At each pocket a notch 70 is provided in the cam surface69, permitting the arm to be swung inward by the spring 68, providedthat the catch 61 previously has been disengaged. 'lhe top ed e 71. p sthel arm 59 is forced downward, a

stated above, it disengages the catch 61, so that the arm 65 becomesfree and is swung inwards by the spring 68, the cutting edge 71 of thearm 65 being thus brought into the position, shown in Fig. 5, i. e. inthe path of the paper-bagd. The incomplete portion of clgarettes hasjust before been introduced into the said bag,'and while the drum isrotated the edge 71 edects a notch in the bag which consequent-,l easilymay be detected and then removed romthe bags end of the arm 65whas acutting afname leaving the machine. Arm 65 is` then removed into theposition shown in Fig. 4 by the cam surface 69, and the arm 59 is raisedby the cam disk 57, so that the catch 61 engages the projection 64. Atthe same' 'lf the 4 the bags contained in the pockets .of the drum d2.

As the drum 42 and the mechanism rotating the same do not belong to thepresent invention, they are not more closely de'- scribed.

ll claim: l

.1. ln a machine for packing cigarettes or similar articles in bags,boxes or the like the combination with a portioning chamber, in whichlthe cigarettes are located upon each other, of a fecler adapted to beforced against the uppermost cigarette in the said chamber and to enterthe chamber, if incompletely illed,' a marking "device past which thebags containing cigarettes move, a catchlngmechanism normally holdingthe said marking device in inoperative posi- ,or similar articles inbags, boxes or the like tion, a motion transmitting device between thesaid feeler and catching mechanism, so that the ieeler, when enteringthe portioning chamber disengages the said marking device and the lattere'ects a mark in the incompletely lled bag, and means for reen aging thesaid catching device.

n testimony whereof l have axed my signature in presence of. twowitnesses.
